Patent DE-3734523-A1 (DE)
Title: Charge-air cooler (intercooler)
Inventor: ZINSSER WERNER
IPC: F28F9/02
Filed: 1987-10-13
Abstract: In charge-air coolers having a so-called sliding tube plate (sheet), the guide region for the sliding tube plate can become warped (distorted) because of the forces occurring during operation. In order to prevent this, the sliding tube plate is firmly connected to the assigned water box, which is provided with claw-like webs which grip outwards and overlap the rim of the guide frame on the outside in the regions in which the guide frame is otherwise not supported. In this embodiment, the water box connected to the tube plate acts like a sort of tie bolt (tensioner) for the guide frame. The novel charge-air cooler is used, in particular, in the case of high charge-air pressures. <IMAGE>

Patent DE-3740521-A1 (DE)
Inventor: HENYCH IVO DIPL ING
IPC: C21C1/10
Filed: 1987-11-30
Abstract: A refractory lining for a Bessemer converter comprises prefabricated elements (5, 6, 7) made of a composite material which may include several layers, for example, layers 9a, 9b made from an aluminum oxide or zirconium oxide material. The lining is capable of being inserted into the metallic casing 4 of the Bessemer converter. In this manner the replacement of the lining of a Bessemer converter, which is necessary from time to time, is much simplified. Due to the short pre-heating time of the proposed lining, preheated standby Bessemer converters are no longer necessary. The converter may include a basic lining of refractory concrete 10, and a layer of sand 11, or the space between the lining layer 9a and the casing 4 may be filled with chamotte or fireclay bound with silicate of sodium which acts as an insulator. <IMAGE>

Patent DE-3800723-A1 (DE)
Title: Soot burn-off filter for diesel engines
Inventor: HEUER JUERGEN DIPL ING
IPC: H05B3/58
Filed: 1988-01-13
Abstract: Electrical heating wires are fitted to the filter candles of a soot filter as regenerating device. The said wires may be connected by thermally conductive wires running essentially transversely thereto. In order to reduce the power consumption for the regeneration, the heating devices can be separately controlled for each filter candle. In heating up, the soot particles deposited directly on the heating element are fired first and transmit the energy released in the combustion to the adjacent particles. This reduces the energy consumption required for regeneration.

Patent DE-3820545-A1 (DE)
Title: Technological spring
Inventor: OTTO GUENTER
IPC: F16F9/092
Filed: 1988-06-16
Abstract: The technological spring operates with liquid and with gas pressure. Arranged in an outer cylinder (1) with a rigid cylinder casing and closed ends is at least one inner cylinder (38) which is at least partially as long as the outer cylinder (1) and is held coaxially in the outer cylinder by means of flanges (9, 10). Also provided in the inner cylinder is a coaxially guided piston rod (37) with a piston (58), this piston rod being passed to the outside in a leak-tight penetration (6). Arranged coaxially between the inner cylinder (38) and the outer cylinder (1) there is furthermore a flexible hose (11). There is thus a first liquid space (22) between the piston rod (7) and the inner cylinder (38) and a second liquid space (23) between the inner cylinder (38) and the flexible hose but a gas-pressure space (21) between the flexible hose and the outer cylinder. Provided between the first and the second liquid space is a nozzle orifice (24) which allows an exchange of liquid between the first and the second liquid space (22, 23) when the piston rod and piston move. During this process, the flexible hose (11) expands to a greater or lesser extent in the gas-pressure space (21) counter to the gas pressure. When the piston (58) plunges into a seat (59a), a seal (58a) situated in the piston, on the one hand, and a sealing cone (60), on the other hand, provide a tight seal (Fig. 5). <IMAGE>

Patent DE-3823535-A1 (DE)
Title: Device for dispensing microfine powder and tablets
Inventor: REENTS HEINRICH PROF DR ING
IPC: A61M15/00
Filed: 1988-07-12
Abstract: To discharge micronised powder in a specific quantity is a problem in process technology which is difficult to solve at the present time, especially if suspensions, that is to say a blend of the powder with liquids, are made impossible by the process. In this invention, a dispensing system is described which permits exact predispensing and, if necessary, can be combined with a vibration-generating system so that it is easier to inhale the active substance. The solution proposed can be produced very economically. It is very environmentally friendly, since no propellant gases are used, nor any battery system. The dispensing system uses its own waste container, so that the whole system can be recycled again. If required, the dispensing system can be used many times by using an exchangeable active substance container. The dispensing system is closed on all sides when not in use, so that no foreign materials or foreign bodies can penetrate in. Each individual active substance chamber can be closed in an air-tight manner.

Abstract: On a base plate (3), which is attachable to a ski (S), of a ski binding (1), a slide (2), which supports the sole holder(s), is mounted displaceably in the longitudinal direction of the ski. For attaching the base plate (3), a fixed bearing (4) and a sliding bearing are provided. The sliding bearing is designed as a clamp (7) which holds the base plate (3) down on the longitudinal sides. In order no longer to use the base plate (3) for force transmission from the slide (2) to the ski (S), but at least to relieve it of forces and in order to be able to design the base plate (3) to be less strong, lateral overlaps of the clamp (7) are vertically removed from the base plate (3). The intermediate spaces thus formed are bridged by parts of the slide (2). A part of the slide (2) extends from the sliding bearing (clamp 7) to beyond the fixed bearing (screws 4) and, in the region of the latter bearing, engages under the base plate (3) on its longitudinal sides.

Patent DE-3904969-A1 (DE)
Title: Method for eliminating dust particles from surfaces in a gaseous environment
Inventor: SCHMIDT-OTT ANDREAS DR
IPC: B08B7/00
Filed: 1989-02-18
Abstract: The method according to the invention eliminates dust particles from surfaces of solid bodies. The method is efficient for particle sizes down to a few nanometers. The solid body (3) to be freed of dust particles is subjected to a beam (8) of electromagnetic radiation flashes. If, at the same time, an electric voltage generated by the voltage generator (6) is applied between the solid body (3) to be freed of particles and a collector electrode (collecting electrode) (5), this results in the particles being detached and eliminated from the solid body (3). The process can be made more efficient by employing a blower (7). Evaporation of the particles does not necessarily occur. The method can be applied, in particular, to the elimination of very small particles from those surfaces, whose being covered by particles during the fabrication of integrated circuits puts at risk the functionality of these circuits. <IMAGE>

Title: Method of reducing noise in pulse-controlled machine - using mean values of wide range of frequencies from pulse generator for processing by pulse width modulator to match control parameters
Inventor: WESCHTA ALOIS DR ING
IPC: H02M1/12
Filed: 1989-04-18
Abstract: A method of noise reduction during the operation of a pulse controller rotating field machine (2) makes use of a range of frequencies from a generator (4). The complete output spectrum of generator (4) is processed within a recognised distribution regime, e.g. gaussian. A mean value for amplitude and pulse width is arrived at which matches predetermined values (Ft and DF) for a single discrete pulse but is made up of the composite noise spectrum from generator (4). Machine control parameters (a) voltage and (f1) pulse width are fed to the PWM (3) from a separate source (not shown) for regulating the main power suoply unit (1). USE/ADVANTAGE - For speed and torque control of rotating machines. Avoids resonance associated with fixed frequency pulsed system and loss generating harmonics in connected equipment. Eliminates need for filters and chokes. Does not require rapid response semiconductors in main power supply.
